You will need to install a user script manager extension to install this script.
This script is intended to circumvent fake news filters that use key word recognition to shadowban comments on YouTube. Type comment, then press Alt+l (lowercase "L" as in lambda)
If you feel like or have evidence your comments are being shadowbanned it may be because of the words you are using. You can use this script to change your comment so that the letters will use a unicode script font, making it more difficult for your comment to be detected as fake news or hate facts.
